in such manner that the printed matter is' always visible on the facesof. the cards, each of which is provided with some form of deviceadapted to engage and support the one ,aboveit.

I have simplified, reduced the cost, and improved the efficiency of thecard-supporting device and have also improved the com struction of-thecard-holding frame, as hereinafter described and illustrated in theaccompanying drawings, in which- Figure -1 is a perspective view of theindex composed of a series of cards and the frame in which they'are heldand supported. Fig. 2 is a perspective view of the frame alone. Fig. 3is ai'ear or back view of a portion or section of the index illustratingthe arrangement of the card tongues, whereby each card is supported onanother be.- low it. Fig; fl is a perspective view illustrating themanner of inserting a card in the frame. Fig. 5 is a perspective viewlifting of a card in rear of one just inserted. Fig. 6 is a back viewshowing a card raised for readjustment after Fig. 7 1s a verticaladjusted and supthe frame.

The frame of my improved index has an oblong rectangular form and isdistinguished by the utmost simplicity of construction, it being.composed of interiorly grooved side bars 1 and top and bottom cross bars2 and 3, all formed of thin sheet metal 'such as tinned iron oraluminum. As shown in Figs. 1 and 2, the flat top cross-bar 2 issoldered or riveted to the one has been inserted. section of cards dulybacks of the side bars 1, so thatt-he grooves ofthe latter are left openor free at the top to permit cards to be slid out of the frame. The bar2 has a downwardly and rearwardly projecting flange 2 which serves as aguide for the cards in that it prevents the tongues of the lattercatching on the rectangular form and bar when cards are slid out of theframe. The bottom cross-bar 3 has an angle form in cross section and isso applied to the ends of the side bars as to practically close theframe at that point, so that it forms a direct support for the bottomcard of a series and thus indirectly for the whole series, whilepreventing their escape downward. By constructing the frame asdescribed, it has due rigidity, also extreme lightness, and maybemanufactured at very small cost, while at the same time adapted to holdcards securely and permit their ready insertion and removal.

The cards, indicated by the numeral 4- Figs. 4 and 6'-have an oblong areprovided with see especially tongues 5 which'are integral portions ofthe cards, the same being formed by an inverted U-shaped cut and bybending backward or outward'the tongues thus formed, so that they rojectat a sharp angle and are thereby a apted'to engage the bottom of thecard above and thus support the latter.

Fig. 1 shows a face view of the frame nearly filled with cards, and allof those above the bottom one supported on the latter. In other words,each card in the series above the bottom one is supported on the one 7below it, its lower edge resting on the tongues 5 of the lowest orbottom card of the series. The arrangement of the cards with reference,to the supporting tongues is best illustrated in Figs. 3, 6 and 7.

Inorder to insert a card in the frame be- Patented Dec. 1'7, 1912:

tween any that may be already in it, one

hand suffices, and it is only necessary to bow the card slightlyoutward, as in Fig. 4, to permit insertion of its ends simultaneously orsuccessively in the grooves of the side bars 1, and then, the card beingreleased, it may be pushed into place, so that its lower edge rests onthe pro ecting tongues 5 of the card below it. In such case, however,the inserted card lies directly in front of another,

and it is therefore necessary to raise the rear one and with it all thatlie above and are supported upon its tongues. In this operation, asshown in Fig. 5, the card behind the newly inserted one 15 seizedbetweenthumb and finger and lifted to the position shown in Fig. 6, andin such case all the cards above it are necessarily raised also, slnceeach rests on the tongues of the next card below it. Practically thisoperation is reversed for removal of a particular card. Thus, the cardseized'andidrawn upward until its lower edge is above or of the cardthatwas in out of and below it, and

to be removed is particular card which is being removed; then, uponbowing the latter, its ends are drawn bars 1, and its tongues are at thesame time sprung outward sufficiently to free them from the bottom edgeofthe card abovel derordinary conditions they retain thevIn'theconstruction of the cards, they may be cutout of large-sheets by meansof a. cutter also constructed to serve as adie in that it resses thetongues outward simultane- Sy with the cutting operation, sothat'unspring or cantthus given and stand perma- =nently at the requiredacute angle. Thus by this construction, the cards themselves areprovided with integral spring supports'for frame.

thus the entire f th '7 beallslid bodily out those above them in the IIt will be seen that .while the angular flower cross-bar 3 supports thelower card'and series above it and prevents e escape of the cards atthat point, the arrangement of the top bar 2 permits them to sired. Italso permits the convenient inser- "tion of all or a series of cards, sothat they course, raises also all the cards that 5. lie above the out ofthe grooves of the side of the frame when debe readily scribed. v i
